There are only 56000 of them. That is it. The whole gargantuan place has a lower total population than my town. The only place I can think of with a lower population of any size is Antarctica with a summer population of 4000. I mean Guernsey island has a larger population and that thing is 25 sq miles, not 836,300 sq miles.
As you may know, 90% of the land mass is covered in ice, some of it 2-3 miles thick. The small population you mention is confined to a coastal strip about 10-30 miles wide in the southern half of the west coast mostly, the east coast has very few people and the ice comes down to the shoreline in many places there. The northern half is almost uninhabited except for the USAF base at Thule.
Baffin Island is similar. It is less glaciated but has a total population of about 10,000 people, despite being one third the size of Greenland and over twice the size of Great Britain. Most of that population is in three or four towns on the coast. Almost nobody lives in the central two-thirds of Baffin Island. There are arctic islands of considerable size in Canada that have no permanent residents or just the staff of radar bases and weather stations.
Victoria Island in the western arctic is also larger than Great Britain, has one town of about two thousand people and another thousand scattered around the coast in much smaller places. Some of the islands north of there are totally uninhabited. If the arctic ever does become ice-free that may change, as there are vast mineral resources up there and some are waiting for more favorable economic conditions to be exploited.
Don’t get me wrong - I’m a great fan of the Danes, especially of Margrethe II.
I’m just wondering how her Greenland subjects would vote, once they ‘got’ here.
